a) A schematic of the “one‐pot” processing for UALPE of h‐BN and ink formulation. b) Rheology measurements of 2‐BE solvent, PU (precursor), PU (precursor)+2‐BE and PU (precursor)+2‐BE+h‐BN. c) Optical absorption spectrum of exfoliated h‐BN in ink. Inset: Diluted sample in cuvette for measurement. d) TGA of the PU precursor with and without h‐BN. Inset: Close‐up of the high temperature region of the TGA measurements. AFM statistics indicating the e) lateral size and f) thickness of exfoliated h‐BN flakes. g) Raman spectra for bulk h‐BN, plain PU precursor, and PU precursor+h‐BN ink. The excitation wavelength is 514.5 nm.
